The present experiment was conducted to investigate the effect of heat stress (HS) andstocking density (SD) on growth performance, breast meat quality, and intestinal barrier functionin broiler chickens. Experimental treatments included two different ambient temperatures (20 °C:thermoneutral conditions, or 27.8 °C: HS conditions) and two different SD (low: 9 birds/m2 andhigh: 18 birds/m2) in a 2 × 2 factorial arrangement. A total of 1140 21-day-old broiler chickens wereallotted 1 of 4 treatments with five replicates. At the end of the experiment (35 days of age), twobirds per replicate were euthanized for sample collections. The results indicated no interactionsbetween HS and SD for all measurements. For main effects, HS decreased (p < 0.05) the growthperformance of broiler chickens. Similarly, high SD also decreased (p < 0.05) body weight gain andfeed intake. HS decreased (p < 0.01) jejunal trans-epithelial electric resistance (TER), whereas highSD did not affect TER. Neither HS nor high SD affected jejunal tight junction-related geneexpressions; however, high SD reduced (p < 0.05) occludin expression. In conclusion, HS and highSD are key environmental factors decreasing broiler performance; however, the interactive effectsof HS and high SD are not significant under the current conditions.

Abstract Oxidative stress seriously affects poultry production. Nutritional manipulations have been effectively used to alleviate the negative effects caused by oxidative stress. This study investigated the attenuating effects and potential mechanisms of dietary taurine on growth performance and meat quality of broiler chickens challenged with hydrogen peroxide (H2O2). Briefly, a total of 192 male Arbor Acres broilers (28-day-old) were randomly categorized into 3 groups: non-injection of birds on basal diets (control), 10.0% H2O2-injection of birds on basal diets (H2O2), and 10.0% H2O2-injection of birds on basal diets supplemented with 5 g/kg taurine (H2O2+taurine). Each group consisted of 8 cages of 8 birds each. Results indicated that H2O2 administration significantly reduced growth performance and impaired breast meat quality by decreasing ultimate pH and increasing shear force value (P &lt; 0.05). Dietary taurine improved the body weight gain and feed intake, and decreased feed/gain ratio of H2O2-challenged broilers. Meanwhile, oxidative stress induced by intraperitoneal injection of H2O2 suppressed the nuclear factor-κB (NF-κB) signaling and initiated autophagy and apoptosis. Compared with the H2O2 group, taurine supplementation restored the redox status in breast muscle by decreasing levels of reactive oxygen species and contents of oxidative products and increasing antioxidant capacity (P &lt; 0.05). Moreover, upregulated mRNA expression of NF-κB signaling-related genes including p50 and Bcl-2, as well as enhanced protein expression of NF-κB were observed in the H2O2+taurine group (P &lt; 0.05). Additionally, dietary taurine decreased expression of caspase family, beclin-1 and LC3-II (P &lt; 0.05), thereby rescuing autophagy and apoptosis in breast muscle induced by H2O2. Collectively, dietary supplementation with taurine effectively improves growth performance and breast meat quality of broilers challenged with H2O2, possibly by protecting against oxidative injury and modulating cell death signaling.

This study aimed at examining the effects of curcumin supplementation on growth performance, antioxidant capacity, and meat quality of ducks. To investigate these effects, 600 healthy ducks were randomly assigned to four treatment groups with 10 replicates pens, and each pen contained 15 ducks. Ducks were fed a diet containing curcumin at levels of 0, 300, 400, and 500 mg kg−1 in different groups. The results demonstrated that curcumin supplementation is beneficial to the growth performance (p < 0.05) of ducks and antioxidant capacity (p < 0.05) of duck meat. In addition, dietary curcumin raised the meat quality of ducks, improving the meat color, increasing water-holding capacity, and inhibiting lipid and protein oxidation. In conclusion, the present study provides important insights into both the nutrient and qualities of ducks, finding that a dietary inclusion of 400–500 mg/kg of curcumin (kg−1) has the greatest effect.

The Impact

A total of 150 broiler chicks were used to determine the impact of dietary cinnamon bark powder (CBP; Cinnamomum verum) on breast meat quality, growth performance, and carcass characteristics of birds under coccidiosis, as one of the protozoan parasitic diseases. A total of 5 replicates of birds received 1 of the following 6 groups for 34 days: control groups (1 and 2) received a basal diet without the addition of CBP or salinomycin; group 3 received a basal diet with 0.066 g salinomycin; groups 4–6 were given a basal diet supplemented with 2, 4, and 6 g CBP/kg feed, respectively. On day 21, 4 × 104/100 µL of Eimeria tenella oocysts/bird were challenged, except for the negative control (NC). At the end of the experimental trial, five birds/group were sampled for carcass characteristics and breast attributes. Overall, emeriosis negatively affects slaughter body mass, carcass yield, and the majority of carcass characteristics in birds, and cinnamon can mitigate these effects. Cinnamon groups, particularly at the 2 g level, alleviated the negative effect on performance caused by coccidia infestation to the same or greater extent as the negative control and salinomycin treatment groups. Furthermore, when compared with the other experimental groups, the addition of cinnamon improved some physicochemical properties with some affecting meat quality, such as decreasing MFI and increasing toughness in cinnamon-treated groups. In summary, it can be concluded that CBP can enhance the shelf life, carcass, and quality of birds’ meat by maximizing the productive performance efficiency and breast meat productivity of birds under coccidiosis infestation. Further research is required to investigate the use of cinnamon to optimize the quality of meat and the productivity of both healthy and diseased broilers.

This research aimed to evaluate the health status, growth performance, and meat quality of African catfish Clariasgariepinus maintained in biofloc and nonbiofloc systems. This study applied 3 treatments with 4 replications, i.e.K500 (control, a non-biofloc system at a fish stocking density of 500/m3), BF500 (biofloc system at a fish stockingdensity of 500/m3), and BF700 (biofloc system at a fish stocking density of 700 /m3). The initial body length andbodyweight of the fish used in this experiment were 10–12 cm and 10–12g, respectively. Feeding was done byusing a commercial feed containing 29.76% protein content. The results showed that fish survival in treatmentsBF500 and BF700 were significantly different (P<0.05) from the control. The growth rate of African catfish in thecontrol (K) was the lowest (3.64 ± 0.56%) among the treatments. The results of the organosensory test showed thatthe application of biofloc systems produced a higher quality of fish meat with a range value of 7–9 compared to thatof the control with a range of 6–7. In conclusion, the application of biofloc systems could improve the fish healthstatus, growth performance, and meat quality of African catfish.

Oxidized Oil

Abstract High environmental temperature due to climate change can accelerate oxidation of feed during storage and preparation. Oxidized feed can cause elevated oxidative stress in live birds, resulting in decreased productivity and meat quality of broilers. The study was aimed to determine effects of feed containing oxidized oil on growth performance, plasma oxidative stress, and breast meat quality of broilers. Male broilers (192; Cobb500) at 21 days old were randomly allotted to 32 pens (8 pens/treatment) and raised for 21 days. The birds were fed feed containing fresh (Control) or oxidized corn oil (5%, Peroxide Value:140) with or without vitamin E (500 IU/kg feed) supplementation. Growth performance, oxidative stress markers in plasma collected at Day 42, and quality parameters of breast meat harvested at Day 43 were determined. Data were analyzed using proc glm and means were compared using Tukey’s studentized range (HSD) test. Oxidized feed and/or vitamin E supplementation did not affect growth performance and plasma DNA and protein oxidation. Oxidized feed significantly increased lipid oxidation and reduced total antioxidant capacity in plasma (P &lt; 0.05) and, interestingly, dietary vitamin E made them worse (P &lt; 0.05), indicating that oxidized lipids in feed can induce oxidative stress in live birds and vitamin E may act as a pro-oxidant in highly oxidized conditions. Although they did not affect sensory and functional properties of chicken breast meat, oxidized feed significantly increased lipid oxidation in cooked meat (P &lt; 0.05) but dietary vitamin E considerably inhibited its development (P &lt; 0.05), indicating that oxidized oil and vitamin E in feed can be accumulated in muscle and act as a pro- and anti-oxidants in meat, respectively. The results suggested that oxidized oil in feed can increase oxidative stress in live birds and susceptibility of breast meat to lipid oxidation, and dietary vitamin E can improve its oxidative stability.
